What is the area of parallelogram RSTU? 21 square units 24 square units 28 square units 32 square units

Debora [2.8K]

Answer: 21 square units

Step-by-step explanation:

We know that the area of parallelogram is given by:-

$A=height\times base$

Let US denote the height of the Parallelogram RSTU with corresponding base ST.

By counting the distance between the points using grids or by distance formula,

US= $|4-(-3)|=|7|=7\ units$

ST= $|-1-(-4)|=|-1+4|=|3|=3\ units$

Now, the area of parallelogram RSTU is given by:-

$A=7\times3=21\ \text{square units}$

Keisha bought 1.2 pounds of Swiss cheese that was selling for $5.95 per pound.

Anna11 [10]

Answer:

Keisha paid $7.0805

Step-by-step explanation:

First of all, you already know that 1 pound equals $5.95. Secondly, you have to solve 5.95 divided by 10, which is 0.595. However, the question is asking for 0.2 pounds! Therefore, 0.595 * 2 = 1.19.

But we're not done yet! We still have to find the amount of money in all. 5.95 * 1.19 = 7.0805 The sum of money in all is $7.0805

Hope this helps!

The product of 9 and t squared, increased by 3 times the sum of 2 and t squared translate into an algebraic expression

elixir [45]

Algebraic expression for the given statement is

$9t^2 + 3(2+t)$

Given :

The product of 9 and t squared, increased by 3 times the sum of 2 and t squared

Product means the multiplication

t squared is $t^2$

The product of 9 and t squared is written as

$9 \cdot t^2\\9t^2$

lets write the expression for 3 times the sum of 2 and t

3 times (2+t)

$3(2+t)$

The product of 9 and t squared, increased by 3 times the sum of 2 and t squared .

Algebraic expression is

$9t^2 + 3(2+t)$
